This monument no longer exists. According to the information provided by A. Gabriel and E. Haspels, it used to be on the western slope of the rocky hill called Nızıllı Tepe, west of the village road between Gökçegüney (old name Tonra) and Yazılıkaya villages (The Monument is called Tonra Patlak in all old references). The first mention of the monument is by Gabriel, but Haspels made its detailed examination and drawings in 1960s. The monument was completely destroyed in the following years. It measured 4.5 x 4.3 m.
